The present invention relates to a manifold for a closed system for endotrachael ventilation and aspiration of a patient, which manifold has an interior manifold chamber that defines a through-going axis through the manifold and a system for endotrachael ventilation of a patient comprising a catheter that extends interiorly of a collapsible shrouding, the system further comprising a first end connected to a vacuum source, and a second end connected to a manifold.
BACKGROUNDFor instance, international patent application No WO98/33536 and U.S. Pat. No. 5,487,381 teach various types of manifolds.
U.S. Pat. No. 5,354,267, by reference incorporated herein in its entirety, discloses a manifold for a closed system for endotracheal ventilation and aspiration of a patient, which manifold has an interior manifold chamber that defines a through-going axis through the manifold. This manifold suffers from a number of inconveniences as regards manufacturing techniques and use. Among others, the prior art manifold does not enable supply of a fluid to the patient via the manifold while simultaneously the patient's respirator tracts are sucked by means of a catheter advanced through the manifold. Thus, the invention aims to provide an improved manifold that can be manufactured in an inexpensive manner and that allows adjustment of a wide variety of operating states.
BRIEF SUMMARY OF THE INVENTIONThe improved manifold is obtained in that the valve body is configured as a segment of the face of a cylinder configured for abutting on the cylindrical portion. When desired, the described configuration of the valve body thus enables flushing of a first section of the manifold chamber without significant risk of the flushing fluid unintentionally penetrating into the second section of the manifold chamber that is in direct communication with the patient. Besides the invention enables an embodiment in which it is possible, in one of its operating states, to block the manifold relative to the supply source for the flushing fluid whereby the risk of unintentional influx of flushing fluid is to a large extent prevented when suction is performed on the patient's respiratory tracts.
By an embodiment including a circular guide track for the valve body interior to the first manifold portion and an embodiment wherein the valve body includes an extreme end and the guide track is configured for receiving the extreme end, the valve body can be caused to cooperate with the manifold chamber in a particularly simple manner for blocking the respective openings.
Additional embodiments of the manifold of the present invention allow supply of fluid to the patient while simultaneously a suction operation is performed by means of the catheter.
In another embodiment, the manifold can be constructed by means of a number of separate components that are connected to each other. Also, the manifold may comprise a peripheral surface area and a bushing, whereby shrouding for the catheter can be secured to the manifold.
The invention will now be explained in further detail with reference to the embodiments shown in the drawings.
In principle, the mode of operation of the system shown in
Additionally and in a conventional manner, the system shown in
To the left in
Additionally, the manifold 100 has a fourth opening (gate) 112 that allows introduction of a flushing fluid into the manifold chamber 102, the packing 104 preventing influx of flushing fluid into the shrouding 50. Flushing fluid can by conveyed from a not shown supply source to the fourth opening 112 of the manifold 100 via a connector element, generally designated by the reference numeral 160 in
More specifically the fourth opening 112 is formed in an area of the manifold wall 101 in the cylindrical portion 125 in a level that coincides with, or approximately coincides with, the axis A. It will be understood that said flushing fluid serves the purpose of cleaning the suction point 44 of the catheter 40 and the packing 104 in the position of the catheter 40 shown in
Besides, the cylindrical portion 125 forms a fifth opening (gate) 122 in the manifold 100. This opening 122 is intended for the mounting within the interior of the cylindrical portion 125 of a turnable cylindrical valve 130 with a valve body 132 that is shown in further detail in FIG. 3. It will appear from
It will be understood that at the transition between the first section 115 and the second section 145, an area will appear whereto the valve body 132 can be turned in a first position. In the following this area will be designated “the passage” 118. The passage 118 may have any expanse along the axis A and also transversally to the axis A; by the solution shown in
The valve body 132 has a peripheral expanse that is sufficient for the valve, in its first position, to cover the entire expanse of the passage 118 transversally to the axis A and for the valve, in the embodiment shown, to block the fourth opening 112 in a second position. The valve body 132 has an end 132′ opposite the cylindrical base part.
The valve 130 shown in
From said first position the valve 130 can be turned about 90° in a first direction to said second position, in which the first 115 and the second 145 sections of the manifold chamber 102 are in communication with each other, and wherein the catheter 40 can be advanced from the left to the right in FIG. 2. In the exemplary embodiment the valve body 132 is located opposite the fourth opening 112 in said second position and thereby cuts off the fourth opening 112, with the result that, to a wide extent, it is possible to prevent influx of flushing fluid into the manifold chamber 102. Said second position of the valve body 132 is outlined in
As mentioned the valve 130 is configured for being able to turn interiorly of the cylindrical portion 125, and to this end the cylindrical base portion of the valve 130 is provided with an operating face that the user can seize with a finger. The valve can be received in close abutment on the interior surface of the cylindrical portion 125 and secured to the cylindrical portion 125 by means of suitable, complementary securing means 125′, eg by being clicked into position. Said securing means 125′ that can be arranged on the outside of the cylindrical portion 125 preferably comprise a turning constrictor whereby the valve can be turned only between extreme positions that define the above-mentioned first and second positions. In the embodiment shown the extreme positions correspond to a turning of the valve of about 90°. Thereby it is possible to avoid unintentional supply of flushing fluid while in a position where the passage 118 is open.
It is possible to provide a solution whereby influx of flushing fluid through the fourth opening 112 is not possible until the valve body 132 configured as the aforementioned segment cuts off the passage 118 completely, ie when the segment has been turned through a given angle about the axis 128 in a direction towards the passage 118. This presupposes a mutual adaptation of the following parameters: The angulation of the opening 112 about the axis 128 relative to the passage 118, the peripheral expanse of the segment 132, and the allowed turning movement of the valve 130.
From
It will be understood that the ventilation stub 1410 can preferably be provided with a screw thread 152 for coupling of a ventilation apparatus thereto. Also, a thread 150 can be arranged on the outside of the manifold wall 101 at the second opening 141 with a view to mounting of a coupling kit for an endotracheal tube, eg of the kind described in the applicant's co-pending patent application.
Albeit in the present text the guide track 103′ is described as annular, the person skilled in the art will appreciate that the guide track 103′ does not necessarily have to extend continuously around the interior surface of the cylindrical portion 125.
